Web (JavaScript)

Drop Dojah’s hosted verification flow into any web page with the Connect widget — a single script, no framework required.

This is a widget SDK — it renders Dojah’s UI with your widget_id and public_key. The Options below are the reference for every web widget; response events and the API-client alternative are covered in Choosing an SDK.

Install

Add the widget script to your page. Don’t use async/defer — the inline code may run before the library loads.

index.html

<script src="https://widget.dojah.io/widget.js"></script>

Initialize

Create a Connect instance with your credentials and callbacks, then open it on a click:

app.js

const options = {
  app_id: "your_app_id",
  p_key: "your_public_key",
  type: "custom",
  config: { widget_id: "your_widget_id" },
  reference_id: "unique-ref-12345",
  metadata: { user_id: "121" },
  onSuccess: function (response) { console.log("Success", response) },
  onError: function (err) { console.log("Error", err) },
  onClose: function () { console.log("Widget closed") },
}

const connect = new Connect(options)
document.querySelector("#button-connect").addEventListener("click", function () {
  connect.setup()
  connect.open()
})

type can be custom, register, or authenticate. Use custom for the EasyOnboard KYC widget; use register or authenticate for EasyAuthentication. That is everything a flow needs — the widget collects the user’s details itself. To skip screens for data you already hold, add the prefill options below.

Prefill known data

user_data, gov_data, and gov_id exist purely to skip screens: user_data for name and date of birth, gov_data for BVN/NIN numbers, gov_id for ID images by URL. Add a key only when you already have a real value for it.

app.js

const options = {
  app_id: "your_app_id",
  p_key: "your_public_key",
  type: "custom",
  config: { widget_id: "your_widget_id" },
  reference_id: "unique-ref-12345",

  user_data: {
    first_name: "John",
    last_name: "Musa",
    dob: "1990-05-16",
    residence_country: "NG",
    email: "john@example.com",
  },
  gov_data: { bvn: "22222222222" },
  gov_id: { passport: "https://example.com/passport.jpg" },

  metadata: { user_id: "121" },
  onSuccess: function (response) { console.log("Success", response) },
  onError: function (err) { console.log("Error", err) },
  onClose: function () { console.log("Widget closed") },
}

gov_id also accepts national, dl, permit, voter, and custom. The values above are the sandbox test BVN and a placeholder host — see Sandbox & test data for the full set of test values.

Omit a key rather than sending it empty. A gov_data: { bvn: "", nin: "" } prefills the screen with blanks instead of skipping it, and the user may be unable to correct it. Every field you do send is PII travelling through the browser, so send only what you actually hold.

Options

Option	Type	Required	Description
`app_id`	string	Yes	Your application’s App ID from the dashboard.
`p_key`	string	Yes	Your public key (safe to use on the client).
`type`	string	Yes	Widget type — `custom` (EasyOnboard KYC), or `register` / `authenticate` (EasyAuthentication).
`config`	object	No	Flow config, primarily `{ widget_id }` from EasyOnboard.
`reference_id`	string	No	Your tracking ID for this session (minimum 10 characters). Comes back in the callback and the webhook so you can match the result to a user. Required when `type` is `authenticate`.
`user_data`	object	No	Prefills `first_name`, `last_name`, `dob`, `residence_country`, `email`. A complete set skips the user-data screen.
`gov_data`	object	No	Prefills government identifiers such as `bvn`, `nin`.
`gov_id`	object	No	Prefills ID images by URL — `passport`, `national`, `dl`, `permit`, `voter`, `custom`. Skips the ID-upload screen for the types you supply.
`metadata`	object	No	Any key/value pairs echoed back to you and in webhooks.
`embed`	boolean	No	`true` renders the flow inline in `container`; `false` (default) opens a modal overlay.
`container`	string	No	CSS selector of the host element when `embed` is `true`.

See Handling the response for the callback model shared by every web widget.

Don’t store PII in metadata or reference_id. Both are echoed back to the client and appear in URLs — use your own opaque identifiers, never a BVN, NIN, or phone number.

Embed inline

By default the widget opens as a modal overlay. Set embed: true with a container selector to render it inside an element on your page instead:

app.js

const connect = new Connect({
  ...options,
  embed: true,
  container: "#embed-container",
})

TypeScript

Connect is attached to window at runtime, so declare it to keep TypeScript happy. Add a types/index.d.ts file and point compilerOptions.typeRoots at that folder:

types/index.d.ts

export {}

declare global {
  interface Window {
    Connect: any
  }
}

Then instantiate it from window:

app.ts

const connect = new window.Connect(options)
